Fly Tying Materials Capps "EASY DUB MICROCHENILLE" x 3 This is a core material for creating the body of flies. It is used by wrapping it around the shank of a hook. Material: It is a string-like material called "chenille," which has short fibers densely packed around a core thread. Features: As the name "micro" suggests, this is a very fine type, suitable for creating small flies or flies that imitate insects with delicate silhouettes (such as caddisflies or aquatic insect larvae). Thank you.
